As U.S. retailers and shopping center owners exhaust domestic growth options and look increasingly outward at offshore opportunities, knowledge and data regarding the state of the industry in target countries is vital. We think nothing of using common quantitative measures to compare economic development across countries - e.g., income per capita, currency stability, interest rates, GDP. It is also taken for granted that certain social indicators provide key initial insights into how a nation is doing - literacy, infant mortality and population growth are examples that immediately come to mind. Without these data, we would struggle to reach even a basic understanding of what is going in the world. Luckily, the data are available for all but a very few countries.
